| 摘 要： | 试验研究了振动搅拌对混凝土强度、含气量和工作性能的影响,结果表明:振动搅拌可以显著提高混凝土强度,但是随着养护时间增长,普通搅拌与振动搅拌混凝土试样强度差异减小;振动搅拌可以显著提高混凝土的含气量;振动搅拌对混凝土粘聚性和保水性影响不大,但是会降低混凝土的流动性。

| Abstract: | In this experiment, the impact of vibratory mixing on concrete strength,air content and working performance was studied. The results show as follow： vibratory mixing can increase concrete strength significantly, but with the increasing of curing time, the strength gap of concrete samples from normal mixing and vibratory mixing is narrowing; Vibratory mixing can increase the air content of concrete markedly; And vibratory mixing has little impact on the cohesiveness and water retention of concrete, but can decrease its flowability. |

| Keywords: | vibrating mixing strength air content flowability |
